摘　　要：将克拉夫-邓肯模型作为传递函数,对水泥土桩荷载传递规律及临界桩长进行了研究,描述了桩周摩阻力的分布及发展规律,并详细讨论了临界桩长的确定标准及各种因素对临界桩长的影响。结果表明,该方法是可行的,该方法同样适用于其它形式的柔性桩。Taking Clough & Duncan’s model as the transfer function, the load transfer and the critical length of cement-soil pile are studied. And the distribution and development rule of the pile skin friction are described. The determination criterion and the influencing factors of the critical length are discussed respectively. The calculation results show that the method is practical and also applicable to other flexible piles.
